TIRES

[robmorg]

28 psi cold seems to be giving me an even tread ware (unlike the OEM tire). If I were a smaller guy, I'd probably run a bit less.

Thanks. I bought one yesterday...

I think you'll be quite happy with that Yoko, Tim. WRT tire pressure, see my response to Peter immediately above. If you are a "normal" weight fellow, you would probably do very well running that tire at 20-22 psi on your RT.

Tires

I dunno IGETAROUND, I think it's more likely that you've chosen a 'less than ideally suited' tire for what you really want from it or want it to do; & then you are setting the tire up for 'failure' in this way by running it at pressures that means it has no chanceof functioning at it's best or even well in the wet, & then you're blaming it for things that really are due to your choices?!? :sour:

Does the weight on the rear tire of your loaded Spyder run as high as 1300 lbs?? If not, then 25 psi is just too high & you will very likely experience increased wear in the centre of the tread, an increased propensity for hydroplaning, and less than ideal traction on all roads but especial on wet roads!!

Ok Peter, you've made a good argument that I'm running too much air pressure. My Kumo is a stock size 225/50R/15. Before you get back to me I will drop to my front tire pressure of 22 psi. Like I said earlier I weigh 235#, I suspect the spyders weight is no more than 300# so put the combined weight with trailer @ 600#. ​

Will try the lower pressures and see if this changes it's wet handling and tendency to hydroplane. Like I said the Conti's on the front are rock solid no matter the amount of water @ 22psi.

Thanks again for your well thought out and supported positions that you take.:bowdown::clap::thumbup:

Al

After due consideration, reduced the fronts to 20 psi and will run the rear @ 18 psi and see what it does for wet and overall handling.

All the great movements in the world began with a cup of coffee!

Al, I love your signature line. But every time I read it, my mind adds the words, "...or a swig of Milk of Magnesia".

Sorry. It's just the way my silly mind works. :sour:

Altimax

We have about 10K miles on our Altimax tire and have not noticed an issue with traction, wet or dry. In fact our experience with this tire is the exact opposite of yours, with and without our trailer. :dontknow::dontknow:


Kent

Same as Kent, 10K plus and have not noticed an issue with wet or dry traction including freeway speeds in pouring rain, both towing and non-towing. Same goes for the federal evo's that so many bash, I run those at 21psi(seems to be the best) and the altimax at 26psi and when tires have to be replaced I will go with same.

I stuck the tire to get a baseline. the two center grooves are 10/32 the two outside groves are 9/32. I'm going to start with 22lbs and check often to see how it's wearing and will adjust psi if needed. Thanks Much. Tim

 

[Highwayman2013]

Not to be contrary but I'm running a Michelin Primacy 215/60/15 at 28 psi for 19,000 miles and it's wearing smoothly. I don't get out in the rain much since I moved to Nevada but it has been in heavy rain without slipping.

my Brain Hurts

So we have Idaho and Remark, both on 2014 RTs, both the same colour so it can't be metal flake extra weight, with one saying the Altimax breaks free incredibly easy in the damp, and one saying it's very solid in the damp. I assume this could only be due to tyre pressures that each is running? This is NOT a statement, but a question from someone whose brain hurts.

Makes you wonder though, how many of those who are having trouble with tyres simply are not running the correct pressure for their particular setup. It certainly appears to be critical based on Peter A's informed explanation.:thumbup:
